Many members use the ceramic pads made by GM as a solution to brake dust. Cuts the dust big time. I had changed for same reason and have been very happy w/ them. I noticed very little difference and I most certainly bedded in my pads good.
As for as stopping power, not quite on par w/ stock or Z06 pads. If you do not race your car then chances of even noticeing a difference are small. GM wouldn't sell inferior pads if they knew Vet owners were driving into back of other vehicles because the stopping power was greatly reduced. From a pure performance standpoint they are not the first choice. As far as the rotors I am not sure whose they are? Again many members use Sportbrakes or buy from Napa as more cost effective. Good luck

I have GM ceramic pads on my car right now with drilled and slotted sport rotors, their great for keeping the wheels clean and the rotors look nice then all I have to do is reinstall stock pads and rotors for the track.

Drilled and slotted rotors are not meant for the track, that is just my opinion. I know the new C6 with Z51 comes with drilled rotors as well as the new Z06 but I think over time they will develop cracks and as far as ceramic pads go, they are great for the street but don't use them on the track.
